not an EP movement
I have seen these before and they have the same movement as the one in the Cairelli (cal 146)
Cairelli had the 146 DP ( 2 counters), this one has the 146 HP ( 3 counters)
The 146 calibers were BEFORE they used the EP
I see Bachmann and Scher says it's an automatic .... That is wrong, the ' from 1985 ' is also wrong
Since it's not an EP but a 146 ( made by Martel, a company Zenith bought in 1960) ... it should be a manual wind
Martel made a few different of these 146 D/H/P and a bigger 156 and 166. These were made between the 1930's and 1970's
When Zenith made their own chronograph 3019PHC they stopped using these hand wound Martel movements
